Specification of Letters Patent.

Patented Oct. 17, 1916.

Application filed January 18, 1916. Serial No. 72,789.

To all whom a may concern:

Be it known that I, GORDON M. BLAN- c-i-mnn, a citizen of the UnitedStates, residing at Spirit Lake, in the county of Dickinson, State ofIowa, have invented certain new and useful Improvements in Music-LeafTurners; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it apper tains to make and use the same.

This invention relates to new and useful improvements in inusic leafturners.

It is the object in general of the present invention to improve thestructure and efficiency of devices of this character, and it 'is morespecifically the object to provide a music leaf turner to whichtheleaves of music may be very readily attached and quickly set foroperation, and operated; the device being of such light and compactstructure that a plurality of such turners may be provided so that thevarious pieces of music to be played may be each associated with aturning mechanism.

It is further an object to provide such a device comprising a relativelysimple structure permitting manufacture at a comparatively low cost.

Vith the above and other objects and advantages in view, the inventionresides more particularly in the novel combination, formation andarrangement of parts as more fully described hereinafter and pointed outin the appended claims.

Reference is had to the accompanying drawings, wherein similarcharacters of reference designate corresponding parts throughout theseveral views, and in which:

Figure 1 is an elevational view of a music leaf turner constructed inaccordance with the present invention, Fig. 2 is a top plan viewthereof, Fig. 3 is an end elevation, Fig. 41 is a central verticalsectional view through the device on the line 4.-4 of Fig. 1, Fig. 5 isa detail sectional View on the line 55 of Fig. 1, and Fig. 6 is aperspective View of one of the releasing pawls.

Referring now more particularly to the accompanying drawing, the body ofthe improved device comprises a frame formed of the top and bottommetallic strips 5 and 6 respectively and the end strips 7 and 8respectively, the strip 8 being disposed at the right hand end of thedevice as shown on the drawings. Extending downwardly from the bottomstrip 6 are leg portions 9 which arecurved r'earwardly and then upwardly and faced with felt orthe like 10 to prevent injury to the pianostructure, these leg portions holding the lower portion of the bodyspaced above the retaining flange of the music rack of the piano onwhich the device is adapted to be placed, so that the turning frames mayfreely swing. In the structure, as shown, two of these turning frames 11and 12 respectively are shown, each comprising top and bottom bars andan outer end bar and these frames are centrally pivoted to the bodyframe by pivot pins 13 which areheld by bracket members 1-1 secured onthe top and bottom strips of said body.

The attaching ends of the frame 11 are reduced in an outwardly offsetmanner and bent at 15 around the pivot pins outwardly of the bracketsand the attaching ends of the frame 12 are reduced in an inwardly offsetmanner and bent at 16 around the pivot pins inwardly of the brackets sothat the frames may swing to lie substantially parallel. For resilientlyurging these frames to the left, a bar 17 is provided transversely atthe central portion of the main frame and having its ends bent laterallyand then inwardly at 18 and secured to the rear of the frame. A secondbar 19 is bolted to this bar and has its intermediate portion bent at 20to provide a bearing member and has its ends bent inward at 21 and ashaft 22 is passed through the bearing 20 and the portions 18 and 21.Springs 23 are coiled about the shaft at the sides of the bearings 20and have their inner ends secured to the said bearing and their outerends extended and secured to the frames 11 and 12. The means for holdingthese frames to the right so that they may be successively releasedcomprises a member 2 1 pivoted to the lower portion of the end strip 8of the main frame and bent in substantially in U-shape to have its freearm engage over the frame and having the extremity of said free arm bentbackwardly to form an actuating finger 25 whereby the member may beswung to release the frame. A similar member 25 of relatively widerbight is provided for engaging the frame 12. These members are adaptedto be actuated in any desired manner as by the strings 27 secured totheir respective fingers.

What is claimed is:

1. A music leaf turner comprising a body frame, a bar connecting theside members of said frame inwardly from their ends, a second barsecured to the first mentioned bar and bent intermediate its ends and atits extremities to form bearing portions, a shaft supported by saidbearing portions, springs encircling said shaft between said central andendbearing portions and each being secured at one end to one of saidbars, sheet supporting frames pivoted to said body frame, the oppositeends of said springs being secured one to each of said frames, and meansfor releasably holding said sheet frames against the tension of saidsprings.

2. A music leaf turner comprising a body frame, a bar, the ends of saidbar being bent forwardly and then inwardly to provide supports, the saidbody frame having its side bars secured to said supports, a second barsecured to the forward face of the first bar and being bent forwardlyintermediate its ends and at its extremities to provide spaced bearingportions, the said ends lying beneath said supports, a shaft extendingthrough said bearing portions and through the bent ends of said firstbar, springs on said shaft, sheet frames pivoted to swing on said bodyframe, said springs being connected to said sheet frames, and means forreleasably holding said frames against the tension of said springs.

In testimony whereof, I aiiix my signature, in the presence of twowitnesses.
